Your boasting is not good. Do you not know that a little leaven leavens the whole lump? 1 Corinthians 5:6 ESV
A leaven is a substance like yeast used in producing fermentation, an irreversible modification or lightening in a dough or liquid. The leaven in a sense damages and destroys the dough or batter. 
Our text reveals that proud talk, or generally sin acts like yeast in our lives. As “just a little yeast makes the whole batch of dough rise”, and eternally changes, in a sense destroys it, even so does just a little sin eternally changes and destroys the believer. Since you’re designed and destined to be an unleavened bread, but have been destroyed by the leaven, there’s therefore only one solution, the sinful self has to be destroyed, and all the old yeast taken out so as to have a new batch of dough. 
Beloved, like the dough cannot deal with the leaven, similarly you cannot deal with the issue of sin in your life. Like the dough with leaven cannot fulfill the destiny of the unleavened dough, neither can you be what you’re destined to be with sin in your life. Sin like cancer has no little one. It’s always deadly and must therefore be dealt with and replaced. This can only be done by the Lord and He will only do it when you come to Him in repentance, with faith in His substitutionary death. Your destiny is in your hand!
Grace upon grace!
